Legendary sound

Infinity's Kappa Series 60.11cs 6-3/4" component speakers continue in the tradition of this legendary line of speakers, offering rugged construction and impressive sound quality. Once installed, this system will bring out every nuance and detail in your favorite music tracks, making time spent in your car seem more like a concert than a commute.

Large soft dome tweeters

If you're looking for natural-sounding high frequencies, Infinity uses edge-driven 3/4" soft dome tweeters in this system. The "edge-driven" design results in a larger tweeter that handles more power and delivers smooth response way down into midrange frequencies not covered by smaller "W"-shaped domes. You'll hear a more clearly defined soundstage where you can picture the placement of every instrument. Infinity includes hardware for surface- or flush-mounting the tweeters, plus Starfish brackets that help you install the tweeters in many factory tweeter openings.

Glass fiber woofer with Plus One+ technology

If you like bass, the Kappa glass fiber woofer holds its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you more surface area than with most comparable speakers. A bigger cone means more bass to complement the superior high-frequency response. The included external crossovers send the appropriate frequencies to the tweeters and woofers.

Great for any system

These 2-ohm speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp — up to 90 watts RMS. Grilles are included.

Note: Infinity describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Product Research

Woofers

Plus One Woofer Cones: The Plus One woofer cones offer more
surface area than other speakers that fit in the same size opening. This is
accomplished by using a new basket design and hi-roll surround. The result is
greater bass output and a significant increase in efficiency.

Formed Glass Fiber Woofer Cones: The formed glass fiber cone
material is very light and extremely stiff, minimizing flex. This results in very
low distortion and improved clarity.

iCGM frames: The Kappa series speaker baskets are made of
composite Injected Carbon Glass Matrix (iCGM). iCGM is lighter and stronger than
stamped steel; it retains its shape, even when mounted on uneven surfaces (common
in car mounting locations), plus offers exceptional damping of any resonances.

Woofer Size: This component set is marketed as having 6-1/2"
woofers; they will fit in standard 6-1/2" speaker openings, but do not use the
standard 6-1/2" speaker bolt pattern. In order to install them in standard
6-1/2" speaker openings you must drill new screw holes. If new holes are
drilled in the mounting surface of the car, no bracket is needed. If drilling in
the car is not an option, the included brackets can be used, which have standard
6-1/2" mounting holes and the Ford non-symmetric four hole pattern. When
using the brackets the depth becomes 1.885" and the mounting height becomes
0.773".

Terminals: The woofers' input terminals are gold-plated set
screws that will accept up to 12 gauge bare wire.

High-Output Design: The high output 2-ohm voice coil design
compensates for the high in-line resistance of small gauge factory wiring and
extracts every watt from factory receivers, increasing overall system output and
efficiency (relative to 4 ohm speakers). The speaker's 2.0-ohm impedance combined
with the impedance of the factory speaker wire presents a true 4-ohm load to your
connected headunit or amplifier. The speakers also benefit from increased power
when you upgrade the wire and add aftermarket amplifiers, designed to power a
2-ohm load.

Tweeters

Edge Driven: The 3/4" edge-driven tweeters use textile
soft domes. An edge-driven tweeter has better dispersion characteristics and allows
for a lower crossover frequency than typical tweeters of the same size, which
improves imaging. The result is improved vocals and musical clarity.

Tweeter Mounting: The I-Mount tweeter mounting system and
Starfish mounting brackets give you several different ways to mount the tweeters:

Surface Mount: Surface mounting the
tweeters involves screwing the surface-mount cup to the
mounting location, then inserting and locking the tweeter
into the cup.

Flush Mount: Flush mounting is made
easy through the use of the threaded flush-mount adapter
and plastic locking nut. Once a cutout is made, the
flush-mount adapter (with the tweeter installed) is
inserted into the hole. The large plastic locking nut
is threaded onto the adapter (from behind the mounting
surface) to hold the complete assembly securely in place.
When flush mounted, the tweeters may be angled for optimum
response and imaging.

Starfish Mounting Brackets: The Starfish mounting
brackets allow the tweeters to be installed in factory locations behind
the grilles:

Surface Mount (behind grille panel): Once
the Starfish bracket is trimmed, it is screwed to the mounting
surface behind the grille panel. Then, the tweeter is inserted
into the bracket and locked into place.

Flush Mount (behind grille panel): Once the
Starfish bracket is trimmed, it is dropped into the cutout in the
mounting surface behind the grille panel. Then, the tweeter is
inserted into the bracket and locked into place.

Bottom Mount (to grille panel): Once the
Starfish bracket is trimmed, it is secured to the underside of
the grille panel. The tweeter must be inserted into the bracket
and locked into place before the bracket is mounted.

Flush Mount (in-dash location): Once the
Starfish bracket is trimmed, it is dropped into the cutout in
the dash. Then, the tweeter is inserted into the bracket and
locked into place.

Crossovers

Crossovers: The crossovers use low-loss air core inductors,
low-hysteresis polypropylene capacitors, and high-quality resistors. Each crossover
has a tweeter output level switch; choose between flat and +3dB.

Connections: Each crossover has set screw input and output
terminals that will accept up to 10 gauge bare wire.

Crossover Dimensions:

Length: 3-3/16"

Width: 4"

Height: 1-3/8"

Power Handling: Although Infinity lists the RMS power handling
as 90 watts, they also list the recommended power range as 5-200 watts RMS. We've
opted to list the more conservative 90 watt RMS figure on the specifications page.

Nice clear sojnd

Exactly what I wanted. While it doesnt sound like an $800 component system but that wasnt what I was expecting from a $250 set of speakers. Add road and engine noise and you won't tell the difference. I drive these with a JL Audio XD400/4 which puts out 100w/channel into these 2 ohm drivers which is more than enough to fill the front with sound. Great middle-of-the-road component speaker and a great upgrade to any OEM stereo system, especially the anemic Boston Acoustics system that came in my Camaro.

Simply Awesome

As with a couple other reviewers, I didn't originally want to spend this much on speakers for a truck that I drove occasionally. However, I got them on a great sale and was glad I did. They installed easily and sound great with the factory head unit and factory amp.

A great sounding speaker

I'll preface this by saying that I hadn't planned on spending this much for a pair of car speakers. I started off with some lesser speakers that, unfortunately, had tweeters too large to go into my intended location (replacing the in-dash drivers in an older Toyota Avalon.) So.. I begrudgingly upgraded, though now that the speakers are installed, have no regrets at all. The sound is smooth, the range is amazing, and the imaging is precise. I lost a bit of volume in the upgrade from factory speakers and think these would benefit from a more potent external amp, but will take the sound quality over quantity, any day of the week. (With limited budget, I'm sticking with the factory external JBL amp for now.) The listener fatigue I had with the factory speakers is gone. There's a slight bit of upper-end harshness to these that I expect will disappear after a few hours of use, but even my non-critically-listening friends can hear and appreciate the improvement. Infinity even supplies curved and flat molded logos to tastefully announce an upgrade hidden behind factory grilles.

Cons:Woofer mounting holes were a bit off for easy installation, even with a variety of Infinity- and Crutchfield-supplied adapter rings. No wire supplied. Knowing this, I bought some 14 ga wire from Crutchfield, but it was too large for the supply of connectors I had. Crossovers didn't offer the same attachment flexibility as other components.

Great Sound

Written By Edgar, Los angeles, CA on Sunday, August 17, 2014

I recently bought these speakers about a month ago. I own a Mitsubishi 3000gt and it has a small interior. My goal was to get really great front speakers since it is a coupe. These speakers are an huge step up from stock speakers and 100 an under aftermarket speakers. What can I say? these speakers provide incredible sound but barely met my expectations for speakers within this price range. Like any component speaker, the high and low frequencies are divided very well by the crossover. The speakers are very loud for their size as well. I am running a kenwood kdc x397 unit with a 100 W max / 55 W rms amplifier. I love the high and mids that the speakers produce but they do lack on bass. At around 60 - 70 % volume the bass reaches its max and distorts a bit. Im running so Pioneer TS-A6975 6x9 in the back. The 6x9 are decent speakers that are very loud and produce great bass; They are my main source of bass in my car. I love these speakers and combined with songs that have great sound quality, not downloaded and converted from youtube, they produce amazing sound. I would recommend these to anyone looking for speakers with great high and mid frequencies.

Pros:great tweeter and I love the ability to switch between 0 dB and +3 dB on the crossovers. The +3 dB gives the speakers less bass and more emphasis on vocal and sound in general.

Ahhh...so much better

It is an amazing upgrade from stock speakers in a 2014 Subaru Outback from Harman Kardon to an aftermarket Infinity speaker made by same company. I did need to add an aftermarket amp to create a good sound in these speakers. The Subaru standard system was poorly designed by Harman Kardon in that almost all the sound was blasting at you from the tweeters designed into the dash and reflecting from the front window. It was unbearable and became so bad I had to keep the volume barely audible and moved to front to back fade 20% front/80% back. Although the sound was good with this speaker set alone...the sound did not round out until I added the component speakers bought on Crutchfield from Infinity. The pricing on the speakers from Crutchfield was much better than at the local shop. Thanks Crutchfield.

Pros:They are a good speaker.

Cons:They don't create a WOW factor and additional amp is needed. They have slight distortion at high volume. Best not to really crank it, but will be plenty loud for some head banging on 60-70% volume. (I had gotten use to a THX system in my prior car...no much will compare).

F-150

Phenomenal difference! I had some 6x8 coax infinitys before switching to these components and the time and effort was well worth it. The tweeters are super clear. They are a little brighter than a silk dome, but cut through the road/ambient noise with ease. The mids are just as impressive, I can't say enough about these speakers, but there are some cons. This is the first time that I've purchased speakers that didn't at least come with wiring, there were no instructions either. The mounting options for the tweeters was a disappointment as well. I originally wanted to mount them in the sail panel to keep them close to shoulder level, but the only basket with a trim ring would have required a huge hole to be cut in the panel, and then the tweeter would be sticking out almost an inch. Not a good look in my opinion. I ended up using the stock location and attaching one of the baskets to the back of the door panel. Looks and sounds great, so I guess it's o.k. in the end.

Potent Speakers Make My Car Fun to Drive Again

I replaced the tired and buzzy OEM speakers on my venerable 1999 Saab 9-5 SE with these beautiful speakers. The Infinity Kappa 60.11cs were a logical choice for replacing the stock Saab speakers, which interestingly enough were also manufactured by Harman-Kardon nearly 15 years ago. Sticking with the family pedigree enabled me to find those rare 2 ohm impedance speakers that were specified for my car's AS3 sound system. (Before starting this project, I decided to keep the stock H-K electronics and not add any aftermarket amplifiers.) The evolution in product design and quality is very noticeable. Be advised that the upgrade is not a simple pull and plug, some minor car modifications are required for the installation. For the front doors, I had to use a Dremel grinder to shave the inside ribs of the OEM mounts, then drill four new screw holes, to accept the 6.5" speakers. For the tweeters in the front dash, I used the supplied I-mount "starfish" fastened underneath a fabricated MDF adapter plate, so that the domes would not interfere with the stock speaker covers. Connections to the auto harness were simplified by using Metra 72-6512 connectors; no harness cuts or splices were required. The improvement in sound quality is remarkable. I mostly listen to jazz; the vocal phrasings, string and wind instruments are very crisp, articulate and well-blended. I like these new speakers so much that I'll probably take them with me when I sell my car several years down the road!

Great upgrade!!

I bought these when they went on sale and couldn't be happier! Replaced the stock component speakers in my Crossfire and even without an amp running to them these sound amazing! They're efficient enough to produce fantastic sound at low RMS but hit them with 60-90 watts and get ready for bliss in your ears!

Pros:Great sound even at low RMS
Superb sound with a dedicated amp
Great build quality

Great Sound

I purchased these speakers to replace the factory Bose speakers. The sound is great. It took some adjusting to get the sound just right but once it was adjusted, I could not have made a better choice for the money. I purchased the amp, wiring and also a pair of Kappa 62's. for the rear. I was familiar with the 62's as I installed in a previous truck.. If this is your choice, you won't be disappointed.

sound great!

they sound amazing! installed in my 2005 Dodge Ram quad cab. mounted the tweeters in the dash, woofers in the front doors. top quality stuff here. they sounded even better after I fixed my wiring that I did wrong. swapped the input with the output of the woofer lol but Crutchfield tech support was just a phone call away and helped me right out! powered with alpine mrx-v70.
